[amibroker] The Sequential signal variations

Trading Reference Links




The system prefers bullish periods.
Even the optimal solution for the bullish 2003 was, in 
general, worse than B&H.
The parameters optimal values are not symmetric.
The optimals of the bullish period do not give any profitable 
solution for the bearish period[s].
For the whole period Jan2000 till now, the best choice was 
suggesting 0 trades.
Buy signals are not bad and, I think, the validity of this 
theory is to "identify low-risk buy and sell zones", as Tom deMark 
suggests.
Here is the code for your further research .
